Pilcrow
In typography, the pilcrow (¶) is a grapheme used to identify a paragraph. In editorial production the pilcrow typographic character is also known as the paragraph mark, the paragraph sign, the paragraph symbol, the paraph, and the blind P. In writing and editorial practice, authors and editors use the pilcrow grapheme to indicate the start of separate paragraphs, and to identify a new paragraph within a long block of text without paragraph indentions, as in the book An Essay on Typography (1931), by Eric Gill.
